My wife’s been asking when I’ll be back to full hardness again... Now I can tell her that she needs to heat it up until it goes blue. Thanks Tony
You need it to go red and then dunk it in cold water... if it goes blue it gets all soft again.
Don't forget to quench it in water....or something.
I'm sorry for my English... I haven't understand the magnet trick at 17:20 ... Could you please explain it again?
Magnetic materials, like steel, have a temperature called the Curie point above which they stop being magnetic. This is a known temperature, so when it stops sticking to the magnet it has reached that temperature.
skyler lehmkuhl ... thank you man! 👍
"That feels so much more like exactly the same." Those words have blighted my married life!
Maybe you guys need therapy. 😁
"1st, trick myself into thinking I'm saving money by not buying one."
I feel like I live by this....
it's served me well. :)
I just bought a mill and a monster lathe so that I can save money. My wife doesn't understand, but if my checkbook ever recovers, I'll show her.
Probably $4 or $500 tap? BTW, an Acme tap is removing a lot more material than a conventional 60 degree tap.
I just bought 2 welders, I have a lathe (just bought a tool post), and I'm looking at a milling machine.. because I need to save money
I needed a transmission for one of my cars, so I bought another car and took the transmission out of it.
I needed an extra set of wheels for rain tires for my race bike, so I bought another bike and took the wheels off.
I have a slight hoarding issue. 1 sprinter van, 1 trailer, 3 cars, 2 motorcycles. Soon to be 3 motorcycles. I'm 23 and I live in an apartment. Yet somehow no complaints.
So... Clickspring makes a video about making his own drill bits... TOT makes a video about making his own taps. Coincidence?
Also, why do those sets always say "Tap and Die?" I've tapped on many of them and I feel fine.
"I think I'm gonna need a bigger tap wrench." Its usually at this moment that taps get broken.
And every time you spot the impact on the shelf, staring at you, trying to convince you it’d be fine this time, you’ve learned from last time and can make it work... or at least I do, “learned” from that mistake too many times now
I was all... "man, those taps look bought, not made, he's better than he gives himself credi.... ohhhhhh"
"I'm no tool maker" as he is in the process of making tools.
just by saying that he became a master tool maker
and then he goes on to explain hes just guessing and using his experience in making tools
hes on the verge of making no sense at all, its coded with irony, like an enigma, but with a metallurgic dialect

I’m a little late for the game, but here is a machinists trick for water quenching:
Add a bit of dish soap to your quenching water! This will result in lower surface tension of the water and increase the surface contact with the to-be-hardened material. Also, forming of bubbles (Leidenfrost effect) is reduced, bubbles forming are much smaller and collapse faster. Therefore, the quench is more uniform. You can actually get away with some oil-hardening materials being quenched that way, due to less stress buildup!
Hey, that's actually a great idea. I will definitely try that 3 years from now when I next need to quench something.
@@HomebrewHorsepower how did it go?
@davidowens8829 Worked great. I actually made up a solution of "super quench" which is dish soap, jet dry, and salt. Works really well.
Bet you weren't expecting a response!
@@HomebrewHorsepower hahahahhahah awesome 3 years later reply.

Literally laughed out loud at 23:48: "Alright. That feels so much more exactly the same." That feeling leads to so many screwed up things in later projects. But at least the tap didn't break after the improvement!
Learned a ton. Sorry if 500 people already left this same comment. Have a good one!
Jesus what an emotional roller coaster. First you pretend to snap the tap and then pretend the hole is too big
He got me on both of them, damn him! LOL!
I'm so glad I found this channel. The things I have learned that I didn't know that I needed to know!
Lots of guys use the 'hole is too big' excuse
Yeah! "NOT FUNNY!!!" hahaha! :D I kind of died twice!
AppleAssassin My heart sank both times. How am I supposed to relax in bed when he's triggering my adrenalin.
That first snap.. :O oh my! I need a new coffee mug now!! It dropped.. Tot will you make me new from steel?
:D
Never joke about blowing a tap apart, I had flashbacks there! That horrible, sudden free movement, the knowledge that now you get to take a detour into tap-extractor land and it might just be easier to start from scratch...
I'm new to machining (currently being trained on a cnc mill in a tool and die shop) and I've had a few taps break, not fun.
some especially tiny taps I might add
M2 Taps, that’s all I’m sayin
tappy tap tap

“If, like me, you’ve tried to shorten the end of a diving board with a pole-mounted pruning saw, you’ll know what I’m talking about.”
Say no more Tony. Say. No. More. .
Metric acme sounds like a terrible desease when Tony says it
While the actual disease is measuring in inch 😂
Imperial acme sounds like plaque all over the world.
Tony, this is awesome! I love not buying the actual thing needed for the job, and spending lots of times thinking, designing, solving and producing a cheaper alternatives... specially when you'll only use it once. It might not be time efficient, but that's how I spend quality time in my life.
Laughed out loud at "alright that feels much more exactly the same"
This hit me in the giggle-dick. I knew I wasn't alone.
Made me laugh as well
Your comment feels so much more exactly the same as what I was going to write. Well done!
I've watched a couple videos on this chanel now and that sentence got me to subscribe! Well played sir
Tony's stupid jokes are the best stupid jokes on TH-cam!
At last I get my Old Tony fix.
Clearly, I am not only, my "Tony" habit is rampant.
as a toolmaker I am amazed what you can do with the proper knowledge and an adequate homeshop
I find it actually kind of funny, so much work for tapping a hole in steel! I just spent less than half an hour cutting grooves into a 1/2" threaded rod with my Dremel, turning it into a tap for threading wood!
Yonatan24 that sounds like a pain in the ass lol
Wright brothers built a airplane in their home shop.
OTTO As a toolmaker, it should be quite obvious what you can do with proper tools and knowledge... Just like any other trade.
Thanks Otto! a little bit of knowledge can be quite dangerous. ;)
That line "Maching is nothing but a series of emotional struggles"... perfect description.
Amazing channel!
Making a acme thread is definitely a "Kings quest" and is one of those top level things to ever make. The tap looks amazing, I would say great job and thanks for sharing your emotional struggles.
Did anybody else jump and say F*!K at 22:40, like a natural reaction to a tap break.
The Spider Kelly oh yes! And then my memory shot straight to all my work pieces that will forever have a small length of tap stuck in them.
Yep! and yep!
I seriously thought Karma was gonna bite Tony in the butt for that little joke. If that were me, the tap woulda broke seconds later.
Just kidding ...
My heart skipped a beat 😅
You should be teaching our teachers. Your presentation is always so straightforward and accommodating without being patronizing or boring. Thanks so much for all the videos!
This channel is kinda like Clickspring's dirty sister. Everyone loves her and you learn a thing or two.
Well, he did use the term "claptrap".
Clapspring?
Springtrap?
Clicktrap?
You ought to watch some AVE BOLTRs.
I almost fell off the chair when you were "just kiddin".
I cried out "NOOOOOOO!";

Great video and shop project Tony! Too bad she didn't got a tool grinder.

This Old Tony: a "home" machinist that gives you a lot more laughs and insight than any "comedy" or shop teacher could ever do. Who knew! (OK, now I'm really intrigued for the Mystery Project. Not that I mind a 26 minute tangent from TOT...)
Esspesso machine ?
Wouldn't be surprised! Perhaps an industrial coffee bean grinder! All joking aside, just from the beefiness of the parts I'm betting towards a bending/rolling/beading attachment.
@@nexus01gr that was a pretty good guess!
A taper to the flutes would push the chips down out of the way (because you were tapping a through hole). Helical flutes would be what you want if you were trying to tap a blind hole.
The way you explain everything is so easy to follow and it gives me the confidence to try making more of my own tools too. Thanks Tony!
you made a tool, to make another tool, to ultimately make another tool
That's exactly what machining is about 👍😁😇
When you get to "master level", you take months to make machines, to make tools, to make other tools, to make the final tool that can be had cheaply and commonly at most Sears right now. ;)
@@73twall You might need to replace Sears with somewhere else now for the younger generation... sigh, like Harbor Freight, LOL
@CCole RC. Ok, this has nothing to do with tools, ToT, or this video, but it reminded me of this line from Tropic Thunder: "I'm a dude, playing a dude, disguised as another dude." - RDJ as the dude playing the dude disguised as another dude...
History is full of tools making tools.
I truly appreciate the mentality of "Why would I buy it when I can just make it". I learned that from my grandfather and it has become part of who I am. Many people have called me cheap because of this but oddly enough (or not) when they need something they cannot just buy at a price they find acceptable I am the one they ALWAYS come to for help.
You skills, knowledge and willingness to share both are truly appreciated. Thank you sir!!! :)
You're right Tony, there are other videos out there. But no one does it like you!
I've never machined, not a metal worker. Just a locksmith. Maybe small tapping at best. This and AvE are by far the highlights of my TH-cam experience.
"Just a locksmith" is like saying "just an air traffic controller"- don't sell yourself short. I've employed a few locksmiths over the years that turned out to be the best mechanics, welders, and fabricators I ever met.

Have you watched any of BosnianBill's LockLab? Now a days he mostly does challenge locks sent in by viewers but his older stuff was a good learning experience.
Turbo Encabulator I used to watch all his videos. They just got repetitive. At the time I was moving into commercial and residential automation so I started losing interest.
Joe 30 pack that's a kind comment, thank you. I've always appreciated the machining quality of a lot of the stuff I work with, between acquiring the tools and their knowledge of their trade ice always held machinists in high regard.
Jared
I agree completely! But his first 800 or so VJOs were pretty good...
Alright, this has to be a team of people making these videos. No one person could be this funny, edit video, and machine tools.
secretly, Tony, AvE, and Clickspring are all neighbors.
And they seem to be breeding a pool of video editors. Soon your TV will be consumed with well lit shots of angle grinders mounted to lathe cross slides.
If only. That'd be the best channel on TV, hands down :)
Although both awesome in so many ways I don't think Click and AvE are compatible, but that's the beauty of diversity.
In all seriousness, who films and edits these?
The grey scotch-brite makes a perfect background!
the grey makes every thing perfect!!!!!
I noticed it on the 3rd shot and was wondering where he got grey pads
from....
i didn't know scotch brite came in boeing grey
I'm betting on it being car floor mats.
Grey scotch-brite is a lot softer and finer than the brown/ochre ones. @wonderwolf303 why do you wonder? is there a any difficulty buying these?
my heart sank when he pretended the tap had snapped lol
Tony, you touched on the reason that the cutting forces were higher than expected for the given diameter of tap.
When you started cutting your acme thread you first cut a 60* thread to relive the stress on your form tool....the same consideration needs to be observed in your acme tap....which is essentially a gang of form tools... commercial acme taps typically transition from a 60* thread into an acme tread over their length.
So in other words, it'll get there over time?
Played my emotions like a fiddle
When the smaller thread went through the hole I laughed so hard actually thought you may have stuffed it up😂
I don’t machine, or fabricate or do anything like this, but goodness your videos sure make me excited for the day that I can learn machining. I’m fascinated by what you do. Also, I appreciate that you bring it down to terms that are easily understandable. Thanks.
Its 1.25AM and I am watching this video of a tool being made which I don’t know what it does and a man using vocabulary that is 70% alien to me and I LOVE IT!
Your very welcome, Thank You for sharing this with us.
My visit into the tap making world was a simple thread clean out tap for a driveline. Just took an extra bolt that hold the U-joint in place and used a dremel and cut some flutes.
Worked well doing the job I needed it to do. Moral of the story. If you need it now and can't wait. Then make it yourself and also save the money.
YESS! More TOT
Its taken him long enough :P
I thought of you while watching the surface grinder: "Time to learn from Tony what Alec said to pay no mind to."
Less yack yack!!
Alec Steele was going to tag you in the video but you beat me to it 😂
Yes, in the rotation!
Nice!
Speaking of getting high speed steel soft during grinding: doesnt matter. Just get on it, annealing Hss is almost impossible without a controlled furnance/kiln.
you can save a lot of trouble just buying cheap HSS... it comes already soft. :)
"Highly Soft Steel" ?
This Old Tony steel starts to lose carbon content once it get to around 2600 but by that point its almost molten so grinding doesnt make that much difference
High Speed Silly.....its obvious.
You need a disclaimer at the beginning, "This video includes powerful hypnotic phrases and imagery- please do not watch whilst driving or operating heavy machinery"....
Most acme taps ideally come in a set: a roughing tap then a finish tap. You're much less likely to break a tap that way. Extremely informative vid.
I want to give Tony a hug. Such an awesome video. So much learnification.
Moment that made me go HUH in this video: 29vs30 degrees, HSS types, grinding wheel types, heat treating how-to, spindexer taper setup. Thank you ToT for being an excellent teacher.
There is a section in the machinist handbook that would show you where you lost a few thou on the profile of that tap. It also has a conversion for "give or take" also a poofteenth , a moonbeam and a smidge. Maybe look for the Australian version they could be metric terms. Fantastic as ever. Love rode mics too.
Where can you buy one of these books?
spuznut Just look up Machinery’s Handbook. They’re past the 30th edition by now, it’s extremely popular and common. www.amazon.com/Machinerys-Handbook-29th-Erik-Oberg/dp/083112900X
> a poofteenth
or as AvE says, "just a blonde one" ;)
learned a lot here!!

Hey there, I'm a big fan of your channel!
Those darn "Just kidding" moments - classic!
I love how you don't allow your instruction to get bogged down in mundane detail.
Specifically around 10:00 when you're talking about lead angle.
"Would it be shallower, steeper? I don't know."
We all know that you know. But you stay approachable and keep us engaged in the matter at hand.
Casual professionalism, you have it in spades. Thanks.
When there is subtitles for the filing, then you know it's a quality channel.
Grinding the back of the flutes will allow the chips to pile up in the thread when you reverse the tap. Most taps are designed with a square back to help keep the chips in the flutes.
wheelitzr2 Thanks for the tip.
excellent point. I should've thought ahead. I wonder if that wasn't why my tap was feeling 'crunchy'.
This Old Tony sorry not to be that guy. I really enjoy your videos! Thank you!
This is quite correct but commercially made taps have a slight clearance angle ground into rear of the thread profile which reduces the torque required to turn the tap.
I had the same thought, but assumed that I was missing something.
Coffee, popcorn, thread cutting and heat treating, best end to a Saturday night ever.
You are a WEIRD date. See you at the support group meeting ;-)

Yep, good one, Tee.
I've never used honey for thread tap lube before, would you recommend for all tapping?
I thought it was Astroglide
Tap Majic, Red Label. None of those fancy other versions. They require perceptibly more force, and that force = more broken taps.
I think it depends on who you are tapping, Oh I mean what you are tapping.
On most of the woodworking channels, they use mustard for wood glue, so why not? I can also authoritatively point out that ketchup and peanut butter will work as thermal grease on the CPU in your computer.
Just make sure you are using the right kind. That looks like a nice clover honey.
Awesome video! Bad ideea to watch it at 5 am when everybody around you is sleeping. Bursting in laughs at that hour upsets the wife...

Well ol' Tony, I, for one, learned a few somewhat unrelated thing that I, for one, will have to admit that I, for one, did not know before. Some of those things include, the processes of hardening and tempering, making a trap, and what is O1 and W1 steel. As always, your teaching style is FANTASTIC, and your somewhat dry and twisted sense of humor are just icing on the cake!
Watching these videos by This Old Tony is becoming a serious problem. I just can't stop!! I'm into binge watching now. Who would have thunk that watching machining / welding videos could be this much fun!
I found your channel like last week and this stuff is so interesting I wanna get a mini lathe and start turning and making stuff. Good job, Tony.
You may want to investigate a 12 step program before you get too deep. It's too late for me and probably the rest of us...
He Alec here to. I thought he would carve it in with his special potato knife. But this way I learned much more. Thanks TOT
I hate when my micrometers are off 3 thou or so-give or take.
I would never have envisaged in a million years watching engineering videos ... until stumbling across yours.
Nice job Tony. I believe W1 is a high carbon steel, but it isn't a high speed steel. The two aren't the same. HSS is also high carbon, but with additional alloys to make it high speed.
Offset thread cutting doesn't require 1/2 the thread angle, and that's a bit of internet forum BS that has just taken off and not even a dose of penicillin seems capable of taking care of that pox! It's a pet hate of mine. So long as the compound is set to LESS than half the thread angle, you're good to go. 29.5 just happens to be chosen as it's half the thread angle (for 60 degree threads) with a bit less for mum. It could just as easy be 27 degrees, 25 degrees, or 29.048921 degrees and nobody will notice the difference. It could also be 0 degrees and then we'd call it plunge cutting ;)
i agree , in UK sliver steel= high carbon not HSS, still very good very video.
Phew! I thought it was just me that had "reasons". Don't feel so alone now . Thanks Tony
Pressing like because reasons.
Awesome video, learnt a ton!
Alec, you know he built this whole thread tap project just to show you how to use your new surface grinder. Glad you stopped in. Now less Yack Yack and get back to more Whack Whack!
More yack yack! We've seen you beat metal into submission for hours upon hours, and it's all pretty much the same. The videos where you do stuff other than only blacksmithing is a good mix.
Whaddaya know... You just mentioned him in your last build and all of a sudden a new vid by TOT. Spooky! ;)
I'd love to see some sort of collaboration between the two of you...
Maybe something involving a forged blank and then using the mill and the surface grinder to help remove some of the need to eyeball things on the belt grinders.
I'm sort of thinking in the direction of the M9 CS:GO bayonet you made, where you also used the mill.
I.e. using his expertise to allow you to to marry the forged damascus steel with more modern and accurate machining techniques.
Enough space there for both of you to shine!
What the.... you're everywhere!
the man of steele! happy to have you watching Alec. I'll have you know I have grinder envy now.
that wobble when you were cutting the flutes gives me the heeby jeebies
nice video, thanks. was just wondering how taps were made yesterday!
a few notes on steel, im not an expert but i know a bit. W1 and O1 (the w stands for water quenching and the O stands for oil quenching) are not actually high speed steels, they are both considered "cold work" steels. in use the steel cant get above its tempering tempratures, with high speed steels the tempering temprature is much higher than on cold work steels.
high speed or hot work steels such as m2 (most drill bits), m4, m42 etc have a significant amount of Molybdenum (thats what the M stands for) alloy, this lets them get hot and still keep their temper, but it also means they need to be heat treated and tempered at much higher tempratures, which makes them more difficult to heat treat and have more problems with scale. they are also more wear resistant than less alloyed steels. for an extreme example, CPM 10V (V stands for Vanadium as the major alloying element) is hardned at 1850-2150F(1010-1175C) and tempered at a minimum of 1000F(540C). this means it cant be heat treated in atmosphere because it will oxidize so badly.
W1 and O1 are similar to echother with the main difference being O1 is more heavily alloyed. the main alloy is Manganese, and this increses toughness and wear resistance. also O1 has a bit more chromium than W1 (.50 vs .15%) this is primarily to increse its depth of hardening and is why it can be oil hardened, it also increses wear resistance.
simpler steels like W1 have a limited depth of hardening, meaning on larger parts they will have a soft core sorunded by hard steel, and need a fast water quench to acheve that limited hardness depth. O1 has enough chromium to increse the depth of hardness and thus can be oil quenched (slower quench) which is easier to controll warpage.
Learning with laughter...what a concept.
I still remember little snippets of things you’ve shown us years after when the planets align and I’m facing a similar challenge.
I’m still working on what’s critical and what allows fudge factor.
Thanks again for an excellent treatment of home shop activity my neighbor says can only be done at a certified machine shop.
Um...who does the certification and who says the certified knows enough to certify...and who authorized them and has the knowledge to authorize....well you know what I mean.
I look forward to each and every one of your installments.
nice build tony. i keep an old toaster oven for tempering . you dont have to worry about over temps that way.
Timely! Long story short I needed to make a hob so i could make a replacement worm wheel for my snowblower. I wound up just buying the worm wheel, but this is about spot on what I imagined my process would look like.
Thanks for doing it in a video so I could know I was right just buying the gear. ;D
Dude, can ya build me a custom tap? I've got $7.63. Hold on, I'll check the couch.
I made one of these a few years back, it was an interesting project. I had a vice with a broken nut. The way I took care of it was to buy a couple nuts and cut another Acme thread, had to make it a second time because the thread was a little lose but it's still in service today. I just cut a thread did not make a tap. Good on you!
I wish I had a teacher like you in technical school. The old craft can be glad that today it is possible to learn from people like you on the web! Cheers
"Hopefully you find something useful in there" the sum total of my tap making experience is hacking "flutes" into an M5 bolt with a dremel cutoff wheel. Now I feel like I could try it myself... if I had some ACME rod... and an oxy torch... and a mill...
LOL - I just watched this video again, 3 years later in Nov 2021... and I thought exactly the same thing as you wrote.
"Shortening a diving board with a long handled pruning saw" 👏😂
Fantastic video.
Concerning your comment about heating up HSS, take a look at Toms Techniques video called Red Hardness where he heats a piece of HSS with a torch, and then shows you how it still cuts steel with no problem.
This at first made me feel like an amatuer in my little shop (never tried cutting a thread on the lathe yet). But then watching your poor man's metal hardening I felt like I could do that (never did annealing before). Thanks for the roller coaster ride of emotional struggles .
I *ALWAYS* enjoy your videos and learn (sometimes even relearn) something from them.
This 1 kinda remind me of stuff my dad used to do. He was always making "special" tools to allow him to fix the car at weird angles from unusual positions. It was either “make a tool to do the job or break a couple of fingers and have them badly set” to reach in and turn some out of the way nut/bolt/screw/etc…
In a perfect world, This Old Tony releases a new video every day.
Oh no, I have to disagree. Every hour!

tappy tap tap.
diamondflaw don’t forget the tap water
It turned out scookem
Omg that brought back some shop memories.
Scookem indeed
it chooches like a bought one
I once used a hacksaw and a bench grinder to turn a zinc coated bolt into a tap before my tapping set had arrived. The hardening was near impossible but at the end it did work.
These "half hour tangents" are actually well worth watching.
They help the rest of us avoid the hassle in deciding if we should make something or buy it of the shelf our selves.
Thus saving us days of weary decision making. ;)
Thanks a million Tony.
Always a pleasure and I use, among others, this channel for winding down from a long day of my own DIY.mistakes.
Twice the price but 4 times the fun...for us... ~¿@ Super nice tap build and I still jerked when you pretended to "Bink" it. It must be a PTSD reaction (not covered in the DMS-5) from breaking every 6-32 in the county on a project. Thanks Tony, Great video.
Pisalchemy+ According to Tom Lipton 6/32 is the tap that he dislikes using the most as it is the easiest to break.
july8xx+ The 6-32 tap is notorious for breaking because of the pitch to root diameter to flute depth is the least ideal, leaving a small margin in heat treating (toughness vs hardness). In my case I was tapping a thru hole in a 1/4-20 SHCS (RC39-45)...not pretty even slightly annealed and 60% engagement.
Acme's aren't much better and that is what makes Tony's "grandma's tap recipe" such a fine build.
With as many times that I’ve watched this I didn’t put 2+2 together. That this is for the ring roller
You should've bought a die to make the tap to thread the hole ;)
Tony bought the lathe, mill and surface grinder to avoid buying the tap. And time, loads of time.
To buy one from where and how much it costs????
No, he should have made a die to make the tap to thread the hole!
And what's wrong if he turns a tap???
as I watched him make the tap, I asked myself why he didn't save even more money by machining the rod too!
Extreamly entertaining and educational. If I had a lathe, I would use it once and then gather dust. I’ll stick to what I do know.......everything else. Thanks Tony. great job.
I will never own a machine shop or so any of these things, but I find these videos oddly satisfying! Thanks old Tony!
so much effort put into these videos!

Excellent educational video!! I didn’t understand some of the big words are the machinist lingo but I got the general drift of what’s happening! I have three wood leaves and have used them for 20 years and I just picked up an FE REED Metal lathe😃😃😃😃😃

Nothing about catching roadrunners, the thumbnail was very misleading.

“Alright, that feels so much more exactly the same!” 😂😂
Best line ever
I am much impressed by your skills in making your own tap. Congratulations. Thanks for showing.
As a retired tool & die maker, I enjoyed your video. As for single point threading on a simple lathe, an old trick when threading to a shoulder, turn the cutting tool upside down, run the carriage backwards ( away from headstock) and in reverse spindle revolution, for right hand threads only. you don't have to cut a relief groove at the shoulder as advancing the tool inward, you will cut a groove equal to your thread pitch. maintain cutting edge on center of course. I'm sure that you spent a lot of time making the tap, but W1 (water hardening) will break very easily with shock as a file would break if you tried to bend it. O1 (oil hardening) is more forgiving but will not have a high hardness for cutting. keep up the nice work. also, if you had a Hardinge tool room lathe, it is the easiest simple lathe I have ever used for single point cutting threads. it is almost impossible to make a bad cut, e.g. missing your index number on the treading dial.
